Abstract: Apparatus for dispensing a mixed multi-component compound, in particular for dental purposes. The adjacent outlet connection stubs of the component-containing containers bear a coupling plate on the end sides for the purpose of connecting a mixing nozzle. Said coupling plate forms a guide, running transversely to the direction of the outlet connection stubs, for a coupling slide with a coupling element which engages over a coupling flange provided on the mixing nozzle. The slide is in the form of a frame and is arranged permanently on the coupling plate.
